Food Truck Repair Built Around Your Service Days

Stainless Interiors and the Seams That Matter

The interior surfaces in a food truck are there to be cleaned, and the seams are what make that possible or impossible. Panels lapped and sealed properly present a smooth surface with no place for anything to collect. Panels butted with an open joint, or sealed with something that has cracked, do the opposite.

So a repair that opens a wall has to close it back to the same standard. We replace stainless sheet with matching gauge and finish, lap and seal the joints properly, and restore coving at the wall to floor junction where the original had it.

Cutting corners here is tempting because the seam is only visible up close, and it is exactly what makes an owner fail a look afterward. We would rather add the four hours it takes to do the joint properly than hand back a truck that has to come back.

• Match stainless gauge and finish to the existing surface
• Lap and seal joints rather than butting them open
• Restore coving at wall to floor junctions
• Use sealants appropriate for a food preparation surface
• Photograph the finished seams for your own records

The Serving Window Is a Structural Opening

The serving window is a large hole cut in the side of the body, and the framing around it is carrying load that the rest of the wall shares. On a box body that means the corner posts and rails around the opening. On a van or step van it means the side structure.

Damage there is structural. A side impact near the window, a window frame that has begun to rack, or a door that no longer closes flush are all reports about the opening rather than the window hardware.

The other common finding is water. The window frame, the shelf that projects from it, and the awning or canopy above are all penetrations through the wall, and the sealing around them takes weather, movement and daily use. We meter the wall below a serving window as a matter of course on these trucks.

Hoods, Roof Penetrations and Everything Above the Line

The exhaust hood is the largest penetration in the roof and it is the one owners are least likely to inspect, because getting up there is inconvenient and the hood works whether or not the flashing is sound. Water entering there runs into the roof structure and along the top of a wall.

Everything else on the roof follows the same rule: air conditioning, vents, the fan, antennas and any rack. Each is a penetration with a sealing service life shorter than the vehicle.

When we have a roof open, we inspect all of them rather than only the one that leaked. Doing eight penetrations in one visit costs a fraction of doing one now and another in six months, and on a truck where every shop visit costs a service day, that consolidation is worth real money.

Propane, Generator and Fuel System Mounting

Propane tanks, gas lines, the generator and its fuel supply are all mounted to a vehicle that vibrates constantly. Mounting that has loosened, lines that have chafed against a bracket, and supports that have corroded are common findings and they are the ones that matter most.

We inspect routing, support spacing, protection where a line passes through structure, and the condition of every mount. Where a line was routed carelessly in the original build, which is frequent on owner built trucks, we reroute rather than reinstalling a problem.

The generator compartment is its own item. Ventilation that has been blocked by a later modification, exhaust routing that has corroded, and mounting isolators that have collapsed all shorten generator life and all get looked at while we are in there.

• Check line routing, support spacing and chafe protection
• Inspect every tank and generator mount for movement or corrosion
• Verify generator compartment ventilation has not been obstructed
• Look at exhaust routing and its isolation from combustible material
• Replace collapsed mounting isolators rather than shimming them

Water Tanks, Waste and Floor Drainage

Fresh and waste tanks carry a lot of weight that moves every time the truck does, and tank mounting is a chronic failure point. A tank that has been working against its straps for two years will eventually take the mounting structure with it.

Below that, the floor is doing hard duty. Water, cleaning chemicals and grease work at any joint in the floor covering, and once moisture gets under it the substrate softens quietly. On a truck with a wood floor over steel, that combination produces corrosion you cannot see.

A worked example: side panel repair at the serving window with stainless interior restoration and reseal, no structural involvement, typically 20 to 32 hours at $210 for $4,200 to $6,720, plus $1,200 to $3,600 in panel, stainless, sealant, hardware and refinish materials.
